History

Formed in 1800 from Adams County, Pickering County and Jefferson County

An old deed may name a county that no longer exists, or a boundary that has since moved.

Washington County was created by the Mississippi Territory from Adams, Pickering (now Jefferson), and territory in present Mississippi and Alabama. In 1809, it lost territory to the creation of Baldwin and Wayne counties and to non-county areas, and in 1812 lost more territory to Clarke County. When Alabama Territory was created from Mississippi Territory on March 3, 1817, Washington became a county in the new territory.
